Um breve vídeo relatando a minha experiencia com os dois rádios na prática GD77 e RT3S.
Retevis RT3S muito mais completo, até 100.000 indicativos na base da memória com o nome do radio operador, cidade, pais etc....
Já o GD77 da Radioddity, mais limitado na questão memoria e informações do visor, porém não deixa nada a desejar na parte operacional.

▸ Larger Capacity Li-Ion Battery - This radio is equipped with a 2200mAh Li-ion Battery. Up to 18 hours working time as well as 48 hours of standby time. This is 30% longer than other DMR HT's. It feels really good in the hand - and is solid but not too heavy. It has crystal clear audio and it's easy to program.

▸ USB Port Charger or Wall charger - A USB port charger or a wall charger are supplied with this radio. For USB port chargers, please note that the USB port and charger adapter can only work with a radio requiring 12V input.

▸ More Operations Available via Keypad - Channel name, TX & RX frequency of a channel, display or hidden frequency, channel number, etc. All these can be modified through the keypad of GD-77. You can program one of the side or top keys to change zones. A big time saver.
